Answer:
2/4 3/6
Step-by-step explanation:
any fraction where the numerator is half of the Denominator
Add like terms
only add x's together
2x+3x=5x
we can't add x's and numbres so
answer is 5x+4
9x40= 360
9x30= 270 so the common factor is 9 I have no idea about the exponent stuff
Answer:
The original piece of wood is 108 cm
Step-by-step explanation:
From the given ratio, the shortest is of the ratio 5 and the longest is of the ratio 7
Let the original piece of wood be x
so the sum of the ratios will be;
5 + 6 + 6 + 7 = 24
the shortest length would be 5/24 * x
= 5x/24
the longest will be 7/24 * x = 7x/24
From the question;
7x/24 -5x/24 = 9
(7x-5x) = 24(9)
2x = 24(9)
x = (24 * 9)/2
x = 108 cm
