If 45% of a number is 63 and 35% of the same number is 49, find 80% of that number.

Step-by-step explanation:

1) Let the number be y

45%of y=63

45y/100=63

Y=6300/45

Y=140

So 80%of a number =80y/100

=80×140/100

=112.

Let the number be y

35%of y=49

35y/100=49

Y=4900/35

Y=140

So 80%of a number =80y/100

=80×140/100

=112.

step-by-step explanation:

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✌✌✌
