Question

5. What is 5¹/2 × 2¹/3?
O A. 13 1/3
O B. 12 7/8
O C. 12 5/6
O D. 13 2/5

Answer 1

C. 12 5/6

Explanation:

(5 + 1/2 ) (2 + 1/3)

5 + 1/2 = 11/2

2 + 1/3 = 7/3

(11/2)(7/3) = 77/6

12 x 6 = 72

77 - 72 = 5

= 12 5/6

Answer 2

C

Explanation:

5
`(1)/(2)` × 2
`(1)/(3)` ← change to improper fractions

=
`(11)/(2)` ×
`(7)/(3)` ← multiply the numerators and denominators

=
`(11(7))/(2(3))`

=
`(77)/(6)` ( 77 ÷ 6 = 12 remainder 5 )

= 12
`(5)/(6)`
