Explanation:

Question 1

A multiple of a number is a product where that number is a factor. So for 10, a multiple of 10 is any product with 10 as a factor. From the vocabulary box, "multiple" fits.

We know that \(4 = 2\times2\), so \(4\times7=(2\times2)\times7 = 2\times(2\times7)\). First, we find \(2\times7\) (a 2s fact) and then double the product (since we have another factor of 2, which is equivalent to doubling). From the vocabulary, "double" is the correct term.

In multiplication, a factor is a number that is being multiplied. For example, in \(a\times b\), both \(a\) and \(b\) are factors. So the term from the vocabulary box is "factor".

Answer:

multiple
