So to find a fraction of a fraction you multiply them both.
So 3/5 multiples by 3/4 is 9/20.
Hope this helps
<span>Congruent triangles are
triangles with the same sides and the same measure of angles. You are given
triangle DEF which is similar to triangle FGH. From the figure, side FH is
larger than side DF. So the statement of them being congruent cancels out. Triangle
DEF is smaller in size than triangle FGH. So they are not congruent. The slope
is defined as the rise over run. Side DF has the same slope as side FH. Sides DE
and FE are proportional to sides FG and HG. Only C and D is correct.

We have five value in the data-set
The third value will be 10 since we want the median to be 10
We want the mean to be 14
To find the mean of a data set, we divide the sum of the values by the number of values
Mean = Sum of values ÷ Number of values
14 = Sum of values ÷ 5
Sum of values = 14 × 5
Sum of values = 70
So we need 5 values that add up to 70, one of the value is 10, which is the median. We would want two values that are smaller than 10 and two values more than 10.
These four value must add up to 70 - 10 = 60
From here we can do trial and error:
Choose any two values less than 10, say 9 and 8
We now have in total 8 + 9 + 10 = 27
We have 70 - 27 = 43 left to find
Choose any two values that are bigger than 10 that add up to 43, for example, 20 and 23
Now we have our 5 values;
8 9 10 20 23
Do the checking bit:
We can see from the set, the median is 10
Mean = [8+9+10+20+23] ÷ 5 = 70 ÷ 5 = 14
We can have values other than 8, 9, 20 and 23 as long as two values smaller than 10 and two values more than 10. All five values must add up to 70.
