\nSophie uses 16 beads to make a necklace. One fourth of the beads are purple. How many of the beads are purple?
\n_____ beads<\/p>\n
\nTotal no of beads used by Sophie is = 16
\na portion of purple beads used = \u00bc
\nTherefore total no of purple beads = 16\u00d7 \u00bc = 4 beads.<\/p>\n

\nJayson baked a pan of cornbread for a family dinner. He cut the cornbread into equal size pieces. At the end of the dinner, there were 2 pieces left. Explain how you find the number of pieces in the whole pan of cornbread if Jayson told you that 16 of the pan was left. Use a drawing to show your work.
\n_____ pieces<\/p>\n![\"Go](\"https:\/\/ccssmathanswers.com\/wp-content\/uploads\/2020\/07\/Screenshot-385.png\")
\nNo of bread pieces left after dinner = 2
\nConsidering 1\/6 of the pan was left, we draw 6 ovals since the denominator is 6. Since 2 pieces are 1\/6 of the pan, we represent them two circles in each oval. Therefore total no of pieces in the whole pan of cornbread are = 6 \u00d7 2 = 12.<\/p>\n<\/a>Test – Page 4 – Page No. 84<\/h3>\n

\nMichael replaced \\(\\frac{1}{3}\\) of the buttons on his coat. If he replaced a total of 3 buttons, how many buttons are on his coat? Show your work.
\n______ buttons<\/p>\n
\nLet’s consider the total no of buttons be X
\nGiven that Michael replaced 1\/3 of his coat buttons which are 3 in number
\nwhich means 1\/3 \u00d7 X = 3
\ntherefore X = 3\u00d73 = 9
\nSo the total no of buttons on his coat are 9.<\/p>\n
\nFour teachers share 3 gallons of paint equally. How much paint does each teacher get?

\n_____ fourths<\/p>\n
\nNo of teachers to share paint = 4
\nthe total amount of paint = 3 gallons
\nSo dividing 3 gallons of paint into 4 equal parts = \u00be
\nTherefore each teacher gets \u00be of paint as their share.<\/p>\n
\nEach shape is 1 whole.

\nA store sold 6 fruit trees. Five of the trees were apple trees. What fraction of the trees were apple trees?
\n\\(\\frac{\u25a1}{\u25a1}\\)<\/p>\n
\nGiven that total of 6 trees were sold
\nno of apple trees are 5

\nChristina and Erin made vegetable trays for a neighborhood picnic.
\nPart A
\nChristina put 15 vegetables on her tray. If \\(\\frac{1}{5}\\) of the vegetables were carrots, how many carrots were on the tray? Make a drawing to show your work.
\n_____ carrots<\/p>\n![\"Go](\"https:\/\/ccssmathanswers.com\/wp-content\/uploads\/2020\/07\/Screenshot-387.png\")
<\/p>\n
\npart of carrots on the tray\u00a0 = 1\/5
\nTotal of carrots = (Total no of vegetables \u00d7 part of the carrots)
\n= 15 \u00d7 1\/5 = 3 carrots.<\/p>\n
\nPart B
\nErin put 20 vegetables on her tray. If \\(\\frac{1}{4}\\) of them were carrots, how many carrots were on Christina’s and Erin’s trays? Explain how you found your answer.
\n_____ carrots<\/p>\n
\nNo of carrots in Christina’s tray = 3
\nTotal vegetables on Erin\u2019s tray = 20
\npart of carrots on the tray\u00a0 = 1\/4
\nTotal of carrots = (Total no of vegetables \u00d7 part of the carrots)
\n= 20 \u00d7 1\/4
\n= 5 carrots.
\nTherefore total no of carrots on both of their trays = 5 + 3 = 8 carrots<\/p>\n
\nMaria has 8 tulip bulbs. She gives 5 of the tulip bulbs to her neighbor. What fraction of her tulip bulbs does she give to her neighbor?
\n\\(\\frac{\u25a1}{\u25a1}\\) tulip bulbs<\/p>\n
\nTotal no of tulip bulbs Maria has = 8
\nNo of tuple bulbs she gave to neighbor = 5
\nTherefore fraction of tuple bulbs she gave =\\(\\frac{5}{8}\\).<\/p>\n<\/a>Test – Page 6 – Page No. 86<\/h3>\n
\nLucy rode her bike around the block 4 times for a total of 1 mile yesterday. Today she wants to ride her bike \\(\\frac{3}{4}\\) of a mile. How many times will she need to ride her bike around the block?

\n______ times<\/p>\n
\nNo of times Lucy rode to complete 1 mile = 4
\nSo in one time, she completes \u00bc mile
\nTherefore to complete \u00be mile, she has to complete = \u00bc + \u00bc + \u00bc, which is 3 times<\/p>\n
