Answer:
3. 1.75
4.0.65
5.63
Step-by-step explanation:
3.) 100%/x%=1.82/0.07
(100/x)*x=(1.82/0.07)*x - we multiply both sides of the equation by x
100=26*x - we divide both sides of the equation by (26) to get x
100/26=x
3.8461538461538=x
x=3.8461538461538
now we have:
0.07 is 3.8461538461538% of 1.82
4.) 100%/x%=3.25/2.6
(100/x)*x=(3.25/2.6)*x - we multiply both sides of the equation by x
100=1.25*x - we divide both sides of the equation by (1.25) to get x
100/1.25=x
80=x
x=80
now we have:
2.6 is 80% of 3.25
5.) Combine like terms: 6 + 3.50 = 9.5 9.5 = 65.50 Solving 9.5 = 65.50
