Find the GCF of each set of numbers 14,35,84

Step-by-step explanation:

14=2×7

35=5×7

84=2×2×3×7

common in each=7

G.C.F.=7

7

Step-by-step explanation:

Lets make an orginzed way to search through

14 - - -(1*14)(2*7)

(1,2,7,14)

35 - - -(1*35)(5*7)

(1,5,7,35)

84 - - -(1*84)(2*42)(3*28)(4*21)(6*14)(7*12)

the greatest common factor here is 7

3/4 ÷ 3/4

step-by-step explanation:

basically divide any proper fraction with itself to fit the criteria.

so if we are using 3/4, then:

3/4 ÷ 3/4 = 1

so 1 is the quotient.

and the numerators for both these fractions is 3.   and if we divide the numerators:

3 ÷ 3 = 1

we see that quotient is equal to our original quotient as well.

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.
