Question 7 Please tell me how to do it Its really difficult for me
Answers
Answer:
1/6
Step-by-step explanation:
(2/3 + 4/9) of 3/5 ÷ 1 (2/3) × 1 (1/4) - 1/3
Here, we use the BODMAS rule, which means, we calculate the series in the following order
B -Brackets
O - Order of
D- Division
M - Multiplication
A - Addition
S - Subtraction
Step 1:
Calculate the Bracket fractions
(2/3 + 4/9)
Take LCM of denominator (3,9) and simplify it. We get,
= 10/9
Step 2:
Convert all mixed fractions into Proper or Improper fractions
1 (2/3) = 5/3
1 (1/4) = 5/4
Step 3:
The given series is (2/3 + 4/9) of 3/5 ÷ 1 (2/3) × 1 (1/4) - 1/3
Write down the simplified series
= (10/9) × (3/5) ÷ (5/3) × (5/4) - (1/3) ∵ ['of' implies 'Multiplication']
As per BODMAS, we first calculate the Division relation.
= (3/5) ÷ (5/3)
= (3/5) × (3/5)
= (9/25)
Now, the series is,
(10/9) × (9/25) × (5/4) - (1/3)
As per BODMAS, now we calculate the Multiplication relation.
= (10/9) × (9/25) × (5/4)
= (1/2)
Now, the series is,
(1/2) - (1/3)
= 1/6 (answer)
