Answer 2

1.
`(3)/(8)`

2.
`(3)/(10)`

Step-by-step explanation:

The problems above tackle on the "multiplication of fractions."

Let's solve.

a.
`(3)/(4)` x
`(1)/(2)` =
`(3)/(8)`

• All you have to do is to multiply the numerator of one fraction to the other, and also multiply the denominator of one fraction to the other.
• Numerator: 3x1 = 3
• Denominator: 4x2 = 8

b.
`(4)/(7)` x
`(21)/(40)` ⇒
`(1)/(1)` x
`(3)/(10)` =
`(3)/(10)`

• All you have to do is to get the "Greatest Common Factor" among the fractions. The GCF of 4 and 40 is 4, so you have to divide both of them by 4. The GCF of 7 and 21 is 7, so you have to divide both of them by 7.
