Answer 1

Answer:

18

Step-by-step explanation:

Divide the total weight of dough by the amount required for 1 pizza

20 $\frac{1}{4}$ ÷ 1 $\frac{1}{8}$ ( change mixed numbers to improper fractions )

= $\frac{81}{4}$ ÷ $\frac{9}{8}$

• leave first fraction , change ÷ to × , turn second fraction ' upside down '

= $\frac{81}{4}$ × $\frac{8}{9}$ ( cancel 81 and 9 by 9 )

= $\frac{9}{4}$ × 8 ( cancel 4 and 8 by 4 )

= 9 × 2

= 18 pizza's
