Welcome to your GRADE 5 END YEAR 2023 MATHEMATICS

GRADE 5 MATHEMATICAL ACTIVITIES HOMEWROK FOR NOV-DEC 2023.INSTRUCTIONS1. CALCULATE AND SUBMIT YOUR ANSWERS ONLINEMULTIPLICATION OF DECIMALS.When multiply a numbers with decimals, we calculate the number of decimal places and we also do so in the answer. If the decimal places are two in the question, they will also be two in the answer.NB: Any number multiplied by a 0 is always 0. We don't write a 0 at the complete end of a decimal place. Example 2. 430 is written as 2.43QUESTIONS ON MULTIPLICATION OF DECIMALS1. 2.3 × 3 =

FRACTIONS

Addition of fractions using L.C.M

Example

2^{1}/_{4} + 5^{2/}_{3}=

Add the whole numbers 2 and 5 to get 2+5= 7.

Find the L.C.M of the denominators 4 and 3 .

4

3

1

The L.C.M of 4 and 3 is 2 ×2×3= 12

Add the fractions using the L.C.M

1/4+2/3 =^{3+8}/_{12 }

Divide 12 by the denominator 4

^{12}/_{4} =3 multiply 3 by the numerator 1 to get 3×1=3

Divide 12 by the denominator 3

^{12}/_{3}= 4 . Multiply 4 by the numerator 2 to get 4×2= 8

Add the fractions ^{3+8}/_{12}=^{11}/_{12 }

Add the whole number to the fraction

7+^{11}/_{12}=7^{11}/_{12 }

WORK TO DO
