Answer:
20%
Explanation:
step 1
Find 50% of x
we know that
50%=50/100=0.50
so
Multiply the number x by 0.50 to determine 50% of x
(x)(0.50)=0.50x
step 2
Find 40% of 50% of x
we know that
50% of x is equal to 0.50x (see the step 1)
40%=40/100=0.40
so
Multiply the number 0.50x by 0.40 to determine 40% of 0.50x
(0.50x)(0.40)=0.20x
therefore
The percent of x is equal to 0.20*100=20%
