Question

write and solve a proportion to answer the problem. don't solve the top left one because it is already solved

Answer 1

We want to find a number that is 110% of 70

110% x

------ = ----------

100 % 70

Using cross products

110 * 70 = 100 *x

7700=100x

7700/100 = 100x/100

77=x

The number is 77
