Answer 1

18

Explanation:

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

20
`(1)/(4)` ÷ 1
`(1)/(8)` ( change mixed numbers to improper fractions )

=
`(81)/(4)` ÷
`(9)/(8)`

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

=
`(81)/(4)` ×
`(8)/(9)` ( cancel 81 and 9 by 9 )

=
`(9)/(4)` × 8 ( cancel 4 and 8 by 4 )

= 9 × 2
