Question

The incorrect step in the given calculation is

• A. Step 4
• B. Step 2
• C. Step 1
• D. Step 3

Answer 1

The correct option is A Step 4

$\text{Performing the calculation we find:}$

$3\frac{2}{3}-1\frac{4}{9}$

$=\frac{11}{3}-\frac{13}{9}$

$=\frac{33}{9}-\frac{13}{9}$

$=\frac{20}{9}$

$\text{Converting}\frac{20}{9}\text{into a mixed fraction}\text{using the relation, we get:}$

$MixedNumber=Quotient\frac{Remainder}{Divisor}$

$⟹\frac{20}{9}=2\frac{2}{9}$

$\text{Now, comparing the correct steps}\text{to the given steps, we find:}$


$\therefore \text{The incorrect step in the given}\text{calculation is}step4.$
