a. 1/4of the sum of 18 and 6

Answer 1

Answer: Required expression:
`\frac14*(18+16)`

Result:
`(17)/(2)`

Explanation:

Given phrase:

Required expression:
`\frac14*(18+16)` ['+' used to express sum, 'x' used in place of 'of']

Since 18+16 = 34

Then,

`\frac14*(18+16)=\frac14*34 \\\\=(1)/(2)*17\ \ \text{[Divide numerator and denominator by 2]}\\\\=(17)/(2)`

Hence,
`\frac14*(18+16)=(17)/(2).`
