Answer:

The answer is 1. 64 and 2. 60

Step-by-step explanation:

Question 7. 75% of what number is 48?

Number = x

75%x = 48

3x/4 = 48 (75% = 3/4)

3x = 192 (Multiplying by 4 at both sides of the equation)

x = 64 (Dividing by 3 at both sides of the equation)

Part 75 Whole 48 Part 100 Whole 64

Question 8. 120% of what number is 72?

Number = x

120%x = 72

12x/10 = 72 (120% = 12/10)

12x = 720 (Multiplying by 10 at both sides of the equation)

x = 60 (Dividing by 12 at both sides of the equation)

Part 120 Whole 72 Part 100 Whole 60

Eduardo has a recipe that uses 2/3 cup of flour for each batch. If he makes 4 batches, how many cups of flour will he need? How

34kurt

Answer:

4 batches: $2\frac{2}{3}$ cups

7 batches: $4\frac{2}{3}$ cups

Step-by-step explanation:

If he uses 2/3 cup of flour for each batch, then that is 2/3 four times, or 2/3 · 4.

$\frac{2}{3}$ × $\frac{4}{1}$

= $\frac{8}{3}$ = $2\frac{2}{3}$

If he makes three more, than that will be 7 batches in total. We can multiply 2/3 by 3 to find out how much will be needed for those extra three, then add that product to $2\frac{2}{3}$ .

$\frac{2}{3}$ × $\frac{3}{1}$
