Question 1
To convert mixed fractions to improper fractions
3
4
7
Multiply the whole number part by the fraction’s denominator.
3 × 7 = 21
Add the product that to the numerator.
21 + 4 = 25
Then write the answer you got on step 2, on top of the denominator.
25
7
Option [2]
Question 2
To convert an improper fraction to a mixed fraction:
???
?
Divide the numerator by the denominator.
??? ÷ ? = ??, 28571429
Multiply the answer’s whole number by the denominator: 14 × 7 = 98
Subtract the product from the original numerator to get the remainder: 100 – 98 = 2
Rewrite the improper fraction as a mixed fraction
???
= ??
?
? ?
Option [4]5
Question 3
The steps for finding the LCM of integers are
▪ Express each number as a product of prime powers.
▪ For each prime factor choose the prime power with largest exponent among all numbers.
▪ The LCM is the product of the chosen prime powers.
Let us express each number as prime factors:
9 = 3 × 3 = 32
8 = 2 × 2 × 2 = 23
6 = 2 × 3
The prime factors are 2 and 3 with the highest power ones being 23 and 32
The LCM is the product of the chosen prime powers. That is
23×32 = ??
Option [1]
Question 4
The steps of finding the LCM for variables are similar to that of integers, but much easier because the
variables are prime factored already.
?2?? ; ??? ; ??3
The biggest power of ? is 2, the biggest power of ? is 1 and the biggest power of ? is 3.
The LCM is thus, ????�
