2 2/5 x 3/7(less) =1 1/35
I only thought of an equation for the less one.
Answer:
Step-by-step explanation:
percent increase = (new number - original number) / (original number) * 100
= (1200 - 840) / (840) * 100
= (360) / 840 * 100
= 0.4285 * 100
= 42.85% rounded to nearest percent = 43% <==
Answer:
The value of x that makes the equation true is 3

Explanation:
From the attached image;
Let us write the mathematical equation of the model.
The long bar means x, while the small squares have a value of 1 each.

solving the equation we have;

Therefore, the value of x that makes the equation true is 3
