Sagot :

Answer:

1) 3/10

2) 1

Step-by-step explanation:

1) Multiply numerator to numerator & denaminator to denaminator. then simplify.

[Numerator]

4×3 = 12

[Denaminator]

5×8 = 40

simpliest form of 12/40 is 3/10.

2) find the reciprocal of the second fraction.

= 18/10

Then, multiply the two numerators and denaminators.

5/9 ÷ 18/10 = 1

5 × 18 = 90

9 × 10 = 90

90/90 = 1.
