Question

Use Associative property for multiplying $15,26,7$.

Answer 1

Step:Finding the product.

Associative Property: It says that the grouping of numbers while performing either addition or multiplication does not change the result of that operation, when operated on three or more numbers, which means

For any three numbers $\text{a, b}$ and $\text{c}$,

$\text{a×b×c=a×(b×c)=(a×b)×c}$

So, $\begin{array}{rcl}& & 15\times 26\times 7=15\times (26\times 7)\\ & & =15\times 182\mathbf{(}\mathbf{using}\mathbf{}\mathbf{BODMAS}\mathbf{}\mathbf{rule}\mathbf{)}\\ & & =2730\end{array}$

Hence, the product is $2730$.
