Answer:
3 1/20
Step-by-step explanation:
First, we will convert the mixed numbers into improper fractions...
9 3/10 (9*10=90+3=93) so the improper fraction is 93/10
5 3/4 (5*4=20+3=23) therefore the improper fraction is 23/4
We then want to make the denominator the same...
93/10 (*4) = 372/40
23/4 (*10) = 230/40
We then put it into the question...
372/40 - 230/40 = 142/40
Lastly, we now need to turn this into a mixed number...
142/40=3.55 so the answer is 3 2/40
3 2/40 in it's simplest form is 3 1/20
Hope this helps!
Answer:

Answer:
Step-by-step explanation:
Given:
The given equation is
We solve the given equation step by step.
Now we will subtract both side of the above equation by 2 for eliminating 2 on left side.
In above equation +2 and -2 is cancelled in left side, so the equation is written as.
Now we subtract 10 - 2 = 8 in right side of above equation.
By cross multiplication we get the equation as written below.
Therefore, we get r = 32 by solved the given equation.
