Pretty sure the answer would be 16.
Because 7.6 rounds to 8 and 1.4 would round up to 2. Then you multiply 8 & 2 and get 16.

121 x 12 = 1452 so over 1500 is not a correct estimate. Less than 1500 is the right estimate

We are given numbers $7 \times 10^9 \ and \ 1.4 \times 10^{12}.$

We need to describe the relationship between above given numbers.

Let us divide second number by first number.

$1.4 \times 10^{12}$ ÷ $7 \times 10^9$ .

On dividing 1.4 by 7, we get 0.2.

And on dividing $10^{12} \ by\ 10^9$ , we get $10^{12-9} = 10^3$

Therefore,

$1.4 \times 10^{12}$ ÷ $7 \times 10^9 =0.2 \times 10^3$ .

$0.2 \times 10^3 =200.$

<h3>Therefore, $1.4 \times 10^{12}$ is 200 times of $7 \times 10^9$ .</h3>
