Answer:
T-X
Step-by-step explanation:
Today=T
Yesterday = X
To find the diffrence you need to subtract Today from Yesterday then you will get your answer
1 3/5 = 8/5
.2=2/100
make an equality:
x/(8/5)=2/100
it kinds looks weird on here but write it out on paper
then cross multiply:
100x=(2)(8/5)
100x=16/5
now divide each side by 100:
x=4/125
same for the second one:
make an equality:
x/2=2/100
cross multiply:
100x=(2)(2)
100x=4
x=1/25
X4=81
x4=3 to the power of 4
x=3
