<span>To find the answer to this equation, use the result of "27 people" who prefer tea. This is equivalent to 3 out of 10 people in the whole survey sample. Using equivalent fractions to find the total sample, we see that "3/10 = 27/x." Multiplying 3 by 9 gives 27, so multiplying 10 by 9 gives a total sample size of 90 people.</span>
If shapes are congruent, then they are mathematically equal (same dimensions, angles etc.). So just locate where the angle x is on both triangles, it should have a value on or a calculable value on the other. If you provide us with the actual sheet I could walk you through it.

Answer: 5/4
Step-by-step explanation:
To get the number of groups of 4/5 are in 1, we divide 1 by 4/5. This will give:
= 1 ÷ 4/5
= 1 × 5/4
= 5/4
<h3>There are 5/4 groups of 4/5 in 1.</h3>
