Answer 3

It appears you're providing mathematical expressions that involve multiplication and division. Let's solve these expressions step by step:

5. $1.5 \times 7.2 / 1.8 \times 7.5$

First, perform the multiplications and divisions from left to right:

$1.5 \times 7.2 = 10.8$

Now, we have:

$10.8 / 1.8 \times 7.5$

Next:

$10.8 / 1.8 = 6$

Finally:

$6 \times 7.5 = 45$

So, the result of the expression is 45.

6. $1.3 \times 6.4 / 0.8 \times 6.5$

Similarly, let's solve this expression step by step:

$1.3 \times 6.4 = 8.32$

Now, we have:

$8.32 / 0.8 \times 6.5$

Next:

$8.32 / 0.8 = 10.4$

Finally:

$10.4 \times 6.5 = 67.6$

So, the result of the expression is 67.6.
