Question

first, find an equivalent expression with a whole number divisor.
$1.17 \div 26$
$11.7 \div 26$
$117 \div 26$
$1,170 \div 26$

Explanation:

Step1: Recall division equivalence rule

To keep the value of a division expression unchanged, if we multiply the dividend by a power of 10, we do not need to adjust the divisor if it is already a whole number. Here, we aim to convert the original implied dividend (matching the first expression) to a whole number while keeping divisor 26 (a whole number).

Step2: Identify valid equivalent expression

For $1.17 \div 26$, multiply dividend by 100:
$1.17 \times 100 = 117$, so the equivalent expression with a whole number dividend (and whole number divisor 26) is $117 \div 26$.
We verify: $\frac{1.17}{26} = \frac{1.17 \times 100}{26} = \frac{117}{26}$

Answer:

$117 \div 26$
