Answer the QUESTIONS OF FRACTIONS 1) CONVERT INTO LOWEST TERM : a) 21/...
FRACTIONS QUESTIONS AND ANSWERS FOR CLASS 5
1. CONVERT INTO LOWEST TERM:
a) 21/35
To convert a fraction to its lowest term, we need to find the greatest common factor (GCF) of the numerator and denominator and divide both by it.
Here, the GCF of 21 and 35 is 7. So, we divide both the numerator and denominator by 7.
21/35 = 3/5
Therefore, 21/35 in its lowest term is 3/5.
2. WHICH IS GREATER?
a) 3/4 1/4
b) 2/6 2/8
c) 12/24 12/45
To compare fractions, we need to have the same denominator. So, we need to convert the fractions to equivalent fractions with the same denominator.
a) 3/4 and 1/4 both have the same denominator 4. Since 3/4 is greater than 1/4, the answer is 3/4.
b) 2/6 and 2/8 can be converted to 4/12 and 3/12 respectively. Now, we can see that 4/12 is greater than 3/12. Therefore, the answer is 2/6.
c) 12/24 and 12/45 can be converted to 15/30 and 8/15 respectively. Now, we can see that 15/30 is equal to 8/15. Therefore, the answer is equal.
3. CONVERT 30/10 INTO MIXED NUMBER OR WHOLE NUMBER:
a) 30/10
To convert a fraction to a mixed number, we need to divide the numerator by the denominator. Here, 30 divided by 10 is 3 with a remainder of 0.
So, 30/10 can be written as 3 or 3 0/10 or 3 0/1.
Therefore, 30/10 as a mixed number is 3.
4. SOLVE:
a) 1/9 2/3
b) 5/6 3/4
To solve fractions, we need to have the same denominator. So, we need to convert the fractions to equivalent fractions with the same denominator.
a) 1/9 and 2/3 can be converted to 3/27 and 18/27 respectively. Now, we can add these fractions.
3/27 + 18/27 = 21/27
21/27 can be simplified by dividing both the numerator and denominator by 3.
21/27 = 7/9
Therefore, 1/9 + 2/3 = 7/9.
b) 5/6 and 3/4 can be converted to 20/24 and 18/24 respectively. Now, we can add these fractions.
20/24 + 18/24 = 38/24
38/24 can be simplified by dividing both the numerator and denominator by 2.
38/24 = 19/12
Therefore, 5/6 + 3/4 = 19/12.
5. FILL IN THE BLANKS:
a) A FRACTION shows part of a whole.
b) A MIXED number combines a whole number and a fraction.
