a. 7x9 +(7x 5/10) b.7x59 +(7x 1/10) c.7x5 +(7 x 9/10) d.7x5 +9/10

Answer 1

Question 3:
8 * 7
`(3)/(4)` ---> Convert into an improper fraction
=
`(32)/(4)` *
`(31)/(4)` ---> Multiply the top and the bottom
=
`(32*31)/(4*4)`
=
`(992)/(16)` ---> Simplify
=62

Question 4.
C is correct.

The total capacity is equal to 7 * 5
`(9)/(10)`. You can split this to 7 * 5 and 7 *
`(9)/(10)`, which is the answer to C.
