Answer: See attached.
Step-by-step explanation:
.70 * x = 9.1
.70/.70 * x = 9.1/.70
x = 13
Hi Jujub! To find the answer in lowest terms, first you have to find the lowest common denominator. To find this, find the lowest common multiple of 75 and 125, which is 375. Now, to make the common denominator, you have to make equivalent fractions. 375 ÷ 75 = 5, and 5 × 25 = 125. So the new fraction is 125/375. Now the same thing for 25/125. 375 ÷ 125 = 3, and 3 × 25 is 75. So the new fraction is 75/375. Now add the new fractions:
125/375 + 75/375 = 200/375
This answer can be simplified to 8/15.

We will calculate the unit conversion factor used to convert its engine displacement from cubic-centimeters to cubic-inches.
The relationships between inch and cm are as follows:

Inches and cm represent units of length.
Made into fractions, 1 inch as the denominator and 2.54 cm as the numerator.

As a unit conversion factor of volume, the numerator and the denominator in cubic.


Thus, we get the unit conversion factor

Let's use this unit conversion factor to calculate its engine displacement in new units.

Note for cm³ units that have been crossed out.
The conversion result is
