65/28 pounfs of candy
Answer:
58
Step-by-step explanation:
follow the pattern. The pattern is to take away 10, for each subsequent number.
The simplest form of 18/45 is 2/5
Let x = the unknown number.
Because three-sevenths of the number is 21, therefore
(3/7)x = 21
That is
(3x)/7 = 21
Multiply each side by 7.
3x = 21*7 = 147
Divide each side by 3.
x = 147/3 = 49
Answer: 49
