Question

Gabriel has 15 5/8 pounds of clay. He will use 7/10 pound to make each bowl. After making 8 bowls he wonders how many more bowls he can make.

Answer 1

7/10 x 8 = 5 6/10
15 5/8 - 5 6/10 = 10 1/40
10 1/40 / 7/10 = 14 9/28
so he can make 14 more bowls and 9/28 of another bowl so you round down to 14 complete bowls.

Answer 2

He can make 14 more bowls.

Explanation:

Given : Gabriel has
`15(5)/(8)` pounds of clay. He will use
`(7)/(10)` pound to make each bowl.

To find : After making 8 bowls he wonders how many more bowls he can make ?

Solution :

Gabriel has
`15(5)/(8)=(125)/(8)` pounds of clay.

For 1 bowl he use
`(7)/(10)` pound.

For 8 bowl he use
`(7)/(10)* 8` pound.

For 8 bowl he use
`(56)/(10)` pound.

The clay left to make rest bowl is given by,

`r=(125)/(8)-(56)/(10)`

`r=(1250-448)/(80)`

`r=(802)/(80)`

From
`(7)/(10)` pound of clay he make 1 bowl.

From
`(802)/(80)` pound of clay he can make
`((802)/(80))/((7)/(10))` bowl.

From
`(802)/(80)` pound of clay he can make
`(802* 10)/(80* 7)` bowl.

From
`(802)/(80)` pound of clay he can make
`14.3` bowl.

i.e. Approximately he can make 14 more bowls.
