What is a Fraction ?
A fraction is written as p/q , where q 
0
It is asked to determine the sum of the fraction
31/4 + 17/3 + 8/18
Taking the LCM of 4 , 3 , 18
LCM of 4 , 3 ,18 is 36
Therefore
(279+204+16) /36
499 / 36
Therefore the best estimate of the sum of the expression given is .

I think the answer is 4/8,btw I'm not too sure about the answer
Is that it the whole question?
Answer: 21/40
Step-by-step explanation:
25+18=?The fractions have unlike denominators. First, find the Least Common Denominator and rewrite the fractions with the common denominator.
LCD(2/5, 1/8) = 40
Multiply both the numerator and denominator of each fraction by the number that makes its denominator equal the LCD. This is basically multiplying each fraction by 1.
(25×88)+(18×55)=?
Complete the multiplication and the equation becomes
1640+540=?
The two fractions now have like denominators so you can add the numerators.
Then:
16+540=2140
This fraction cannot be reduced.
Therefore:
25+18=2140
