The solution of 
is 
<em><u>Solution:</u></em>
Given that we have to find the solution of
To solve the given sum, first make the denominators of both the fractions same
This can be done by taking L.C.M of both denominators
<em><u>Step 1:</u></em>
L.C.M of 4 and 7:
The prime factor of 4 = 2 x 2
The prime factor of 7 = 7
For each prime factor, find where it occurs most often as a factor and write it that many times in a new list.
The new superset list is
2, 2, 7
Multiply these factors together to find the LCM
LCM = 2 x 2 x 7 = 28
Thus L.C.M of denominators is 28
<em><u>Step 2:</u></em>
Solution of
Multiply the denominator by a number to get 28 and multiply that same number with numerator also
Thus solution of is
Answer:
3/4
Step-by-step explanation:
She used 1/4 of each of the 3 paper, so in total she used:
1/4 + 1/4 + 1/4 = 3/4

Answer:
<u>The two numbers are 23 and 56</u>
Step-by-step explanation:
Let's say the two numbers are A and B.
We are told:
1) A+B=79
2) 3A+5B=283
Let's take the first expression and solve for A:
A+B=79
A=79-B
Now use this value of A in the second expression:
3A+5B=283
3(79-B)+5B=283
237-3B+5B=283
2B = 46
B = 23
Since B=23, we know from 1) that
A+B=79
A+23=79
A = 56
<u>CHECK:</u>
Does A+B=79?
56+23 = 79? <u>YES</u>
Does 3A+5B=283?
3(56)+5(23)=283
168 + 115 = 283? <u>YES</u>
