4/7 x 9/20 will give brainliest

9/35 (Already Simplified)

Step-by-step explanation:

For fraction multiplication, multiply the numerators and then multiply the denominators to get

4×97×20=36140

This fraction can be reduced by dividing both the numerator and denominator by the Greatest Common Factor of 36 and 140 using

GCF(36,140) = 4

36÷4140÷4=935

Therefore:

47×920=935

Solution by Formulas

Apply the fractions formula for multiplication, to

47×920

and solve

4×97×20

=36140

Reduce by dividing both the numerator and denominator by the Greatest Common Factor GCF(36,140) = 4

36÷4140÷4=935

Therefore:

4/7×9/20=9/35
