When you are multiplying two numbers with decimals, it's easy to do.
First, multiply the numbers as if there were not decimals there:
~5.8
x8.7
____
~406
464
_____
5046
... then, count the number of places for the decimal points, and add them together. 5.8 = 1 decimal place, 8.7 = 1 decimal place, the two added together are 2 decimal places. So your answer, 5046 needs to have two decimal places; or 50.46
(I'm sorry, I had to use a ~ to keep spacing correct... I'm having problems pushing a nbsp into the code... lol)
58% of 150 = 87 (150 / 100 x 58 = 87)
-87
The GCF is 29.
58 divided by 87 = 66.67%
GCF(58, 29, 87) = 29.
58 * 7 = 406
58 multiplied by 70 is 4,060.
The greatest common factor (GCF) of two numbers is the largest number that divides both numbers evenly. To find the GCF of 58 and 87, you can list the factors of each number and identify the largest number they have in common. The factors of 58 are 1, 2, 29, and 58, while the factors of 87 are 1, 3, 29, and 87. The greatest common factor of 58 and 87 is 29.
3 multiplied by 29 equals 87.
87 x 66 = 5742
8 x 87 = 696
35 multiplied by 87 is 3,045.
