7 x 1/8= Explain your answer

7/8  or .875 (depends on if your teacher wants it in fraction or decimal form)

Step-by-step explanation:

Multiplying by 1/8 is the equivalent to dividing by 8. So 7 divided by 8 is equal to 7 x 1/8, which is 7/8 or .875 (again depends on if your teacher wants it in fraction or decimal form)

7/8

Step-by-step explanation:

7 x 1/8 =

7/1 x 1/8 =

7/8

because thats how multiplication works, there is no other way to explain, you cant just explain the steps when the questions are simple. Just show enough work and use that as the "explanation"

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.
