Find the rate and unit rate of 6 calculaters cost $140.00

this is a fraction equal to

6 rate ÷ 140 unit rate

we want a unit rate where

1 is in the denominator,

so we divide top and bottom by 140

6 rate ÷ 140

140 unit rate ÷ 140

=

0.04 rate

1 unit rate

=

0.04 rate

unit rate

= 0.04 rate per unit rate  

i think this might be the answer but not shure

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✌✌✌
