Answer:
220.8
Step-by-step explanation:
Equation: x/69=320/100
x is the # your trying to solve, 320 is the percent so that has to be over 100.
Solve: cross multiply
69*320=100x
22080=100x
220.8=x
320% of 69 si 220.8
If you are looking for 83 = x/9, then you must multiply 83 by 9 to get the numerator.
83 x 9 = 747.
If you are looking for x/83 = 9, then you must multiply 83 by 9 to get the numerator.
83 x 9 = 747.
Your missing whole number is 747.
Hope this helps!
56/72 can be simplified to 14/18, then to 7/9 *dividing by 4, then by 2*
28/32 can be simplified to 7/8 *dividing by 4*
70/90 can be simplified to 7/9 *dividing by 10*
7/9 and 7/9 are equivalent, so 56/72 and 70/90 are equivalent.
6x-18
you pretty much h just multiply both the first part of the parentheses by the number outside, then the second :)
