The difference between a number x and 17 is 21.

38

Step-by-step explanation:sure

X-17=21

X=21+17(when we transpose -ve becomes positive)

X=38

x = 38

Step-by-step explanation:

The difference between a number x and 17  = x-17

which is equal to 21

so,

x-17=21

add 17 on both sides

⇒x=21+17

∴x = 38

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.
