Answer:
Operations on fraction
Fractions represent equal parts of a whole or a collection. A fraction has two parts. The number on the top of the line is called the numerator. It tells how many equal parts of the whole or collection are taken. The number below the line is called the denominator.
Answers:
1.3/7
2.1- 1/5
3.1/12
4.41/42
5.2/5
Solutions:
1. 5/7 -2/7 = 3/7
2. 9/10 +3/10 =12/10 = 1 2/10 = 1 2/10 ÷ 2/2 = 1 1/5
3. 3/4 - 2/3 =3(3)/12 -(4)(2)/12 =9/12 -8/12 = 1/12
4. 5/6 +1/7 = (7)(5)/42 + (6)(1)/42 = 35/42 +6/42 = 41/42
5. 9/10 - 3/10 - 2/10 =6/10 -2/10 =4/10 ÷2/2 = 2/5
6. 2/7+ 3/7 +5/7 = 5/7 +5/7 = 10/7 = 1 3/7
Things to Remember:
-Similar fractions are fractions having the same denominators.
-Dissimilar fractions are fractions having different denominators.
-To add and subtract similar fractions, simply add or subtract their numerators and copy the denominator.
-To add and subtract dissimilar fractions, change the fractions to similar then perform the indicated operation.
-In changing dissimilar fractions to similar, use the least common multiple of the numerator and denominator.
