Question 2. Solve using tape diagrams. a. There are 48 students going on a field trip. One-fourth are girls. How many boys are going on the trip? Answer: 36 boys are going on the field trip.
Explanation: As 48 students are going on a field trip in this \(\frac{1}{4}\) are girls. Hence 36 boys are going on the field trip. \(\frac{1}{4}\) × 48 = \(\frac{48}{4}\) = 12 12 × 3 = 36
Explanation: The smallest angle given is \(\frac{3}{8}\) and the largest angle is 160°. 160 × \(\frac{3}{8}\) = \(\frac{480}{8}\) = 60 160 + 60 = 220 360-220= 140 Hence the value of angle a is 140°
c. Abbie spent \(\frac{5}{8}\) of her money and saved the rest. If she spent $45, how much money did she have at first? Answer: Abbie had $72.
Explanation: 45 ÷ \(\frac{5}{8}\) = 45 × \(\frac{8}{5}\) = \(\frac{360}{5}\) =72
d. Mrs. Harrison used 16 ounces of dark chocolate while baking. She used \(\frac{2}{5}\) of the chocolate to make some frosting and used the rest to make brownies. How much more chocolate did Mrs. Harrison use in the brownies than in the frosting? Answer: Mrs. Harrison use 3 × \(\frac{1}{5}\) chocolate for the brownie
Explanation: Harrison used 16 ounces of dark chocolate. She used \(\frac{2}{5}\) of the chocolate to make some frosting and the remaining to make brownies. 16 × \(\frac{1}{5}\) = \(\frac{16}{5}\) = 3 × \(\frac{1}{5}\) Hence, Mrs. Harrison use 3 × \(\frac{1}{5}\) chocolate for the brownie.
