Answer:

The least common denominator of the fractions is 24

Step-by-step explanation:

we know that

The least common denominator (LCD) is the smallest number that can be a common denominator for a set of fractions

we have

7/8

Multiples of 8 -------> 8,16,24,32,...

5/6

Multiples of 6 -------> 6,12,18,24,...

24 is a common multiple of 6 and 8. It is their lowest common multiple

Alternative Method

we have

$8=2^{3}$

$6=2*3$

The least common multiple are those common and non-common numbers with the greatest exponent

$lcm= 2^{3}*3=24$

Area of the parallelogram = 20 x 16 = 320
Area of the triangle on top = 1/2 x 20 x 8 = 80
Total = 320 + 80 = 400 square inches

Answer:

You can round up to tenths, hundredths, thousandths, or tens, hundreds, and thousands. Some numbers, they have remainders when divided, so you would round them up to make them whole numbers or non-repeating decimals.

Hope this helps!!
