To solve the given expression, follow these steps:
Step 1: Simplify the terms inside the parentheses. Step 2: Perform the subtraction inside the parentheses. Step 3: Multiply the result from Step 2 by the first fraction. Step 4: Simplify the fractions in the second parentheses. Step 5: Add the results from Step 3 and Step 4.
Let's proceed with the calculations:
Step 1: Simplify the terms inside the parentheses: 1 1/2 - 3/5 To subtract fractions with different denominators, we need a common denominator. The common denominator for 2 and 5 is 10.
1 1/2 = (2*1 + 1)/2 = 3/2 3/5 remains the same.
Step 2: Perform the subtraction inside the parentheses: 3/2 - 3/5 To subtract fractions with the same denominator, simply subtract their numerators:
(35 - 32) / 2*5 = (15 - 6) / 10 = 9 / 10
Step 3: Multiply the result from Step 2 by the first fraction: 4 1/6 * (9/10)
To multiply a whole number by a fraction, convert the whole number to a fraction by giving it a denominator of 1.
4 1/6 = (6*4 + 1) / 6 = 25/6
Now, multiply the fractions:
25/6 * 9/10 = (259) / (610) = 225 / 60
Step 4: Simplify the fractions in the second parentheses: 3/4 + 5/6
To add fractions with different denominators, we need a common denominator. The common denominator for 4 and 6 is 12.
3/4 = (33) / (43) = 9/12 5/6 remains the same.
Step 5: Add the results from Step 3 and Step 4: 225/60 + 9/12
To add fractions with the same denominator, simply add their numerators:
(225 + 9) / 60 = 234 / 60
Finally, simplify the fraction:
234/60 can be reduced to its simplest form by dividing both the numerator and denominator by their greatest common divisor, which is 6:
234/60 = (639) / (610) = 39/10
So, the final result of the expression is:
4 1/6 * (1 1/2 - 3/5) + (3/4 + 5/6) = 39/10
