A simple way to solve fraction divided by while number problems is to multiply the denominator and the whole number together, but that only works if the numerator is 1, which in this case, they were all in fact, 1s.
3/15 = 1/5
12/60 = 1/5
So the answer is true
3 over 15 equal 12 over 60
Hope I can help you :)
Answer:

Step-by-step explanation:
See attachment for grid
From the attachment:
There are 10 cells on the horizontal axis and there are also 10 cells on the vertical axis.
This implies that, the measurement of each cell is:



The horizontal axis has 7 selected cells.
This measures

The vertical axis has 4 selected cells.
This measures

So, the selected area is:


or

Given that ∠CEA is a right angle which has been bisected by BE, then:
∠CEB=∠BEA
thus each angle will be complementary to each other, hence the size will be:
90/2=45°
hence the correct statement.
<span>m∠CEB = 45°</span>
