5v -

=

Multiply both sides by 10
50v - 4 =

Divide the fraction
50v - 4 = 8 Add 4 to both sides
50v = 12 Divide both sides by 50
v =

SImplify the fraction
v =
12 1/2 (12x2+1)= 25/2
25/2 x 8/5 (we have to multiply8/5, not 5/8), so =200/10=20
answer is 20
Dividing by 2 is the same as multiplying by 1/2.
2462 * 1/2 = 1231
10 to the 5th power is 100,000. 2 X 5 is 10.

the answer is 1,000,000. (one million)
It's 84. 560 / 100 = 5.60
