A. 1/100 * x = 7
x = 7 * 100/1
x = 700
b. 50/100 * x = 33
x = 33 * 100/50
x = 66
c. 3/100 * 100 = 3
d. x/100 * 200 = 6
2x = 6
x = 3
e. 15/100 * 40 = 6
Answer:
hope this helps you out good luck
To find the value of x let's make the situation a bit easier
3x+10+70=180
3x+80=180
3x=180-80
3x=100
x = about 33.33
Well, 2/4 is equivalent to 4/8. So you can turn the 2/4 into 4/8 and then add 4/8 plus 3/8.
