What is
3/4X5/6
A)1/2
B)1/3
C)2/3
D)5/8

5/8

Step-by-step explanation:

When multiplying two fractions together, always try to cross-cancel if possible as your first step.

In this problem the 3 and 6 reduce to 1 and 2.

Next we simply multiply across the numerators and multiply across the denominators and we have our answer which is 5/8

7! = 7×6×5×4×3×2

3! = 3× 2

as 7! is multiple of 3! because 7! contains 3! that is 3× 2 as factor

so 7! /(3! ) = 7× 6× 5× 4

= 42 × 20

= 840

its b) 840✌✌✌
