Step-by-step explanation:
You have 3/5 of an apple pie" means you have 3 pieces of the 5-piece pie
"You divide the remaining pie into 5 equal slices." means
(3/5 pie) / 5
The math:
(3/5 pie) / 5
is also
(3/5 pie) * (1/5) [to divide by fraction 5/1, invert to 1/5 and multiply]
is also (1/5) * (3/5 pie)
[This means 1/5 of the 3/5 of a pie that is left of"]
So,
each slice is (1/5)*(3/5) pie = 3/25 pie [multiply numerators and denominators]
These ones always feel weird. But we will read the problem directly and do what it says.
So it is 3/5 divided by 5.
Or 3/5/5.
But that looks really weird, so lets think of it like multiplying by 1/5 instead (which is the same as dividing by 5)
So, (3/5) * (1/5) which equals 3/25.
Everyone gets 3 twenty fifths of a pie.
Answer:
3/20
Step-by-step explanation:
15 and 100 both have a common factor of <em>5</em>. To simply an expression, you have to get both the numerator (top number) and the denominator (bottom number) to be as low as possible (to make it so that both can't be divided anymore or don't have shared factors). We divide both sides by 5 (which still retains as an integer and has the same value) and so 15/3=5 and 100/5=20.
Have a nice day! :)
Answer:
87.5cm²
Step-by-step explanation:
area of trapezium = 1/2 (a+b)h
1/2 × (10 + 15) ×7
1/2 × 25 × 7
1/2 × 175 = 87.5
