- 2/9 x 1/7

To multiply the given fractions, we simply multiply the numerators together and the denominators together.

(-2/9) x (1/7) = (-2 x 1) / (9 x 7) = -2/63

So, -2/9 x 1/7 = -2/63.

1.78 x 0.005

To multiply the decimals, we can ignore the decimal points and treat the numbers as whole numbers. After multiplying, we will adjust the decimal point in the result.

1.78 x 0.005 = 178 x 0.005

Multiply as whole numbers:

178 x 0.005 = 0.89

Adjust the decimal point:

0.89 = 0.89

So, 1.78 x 0.005 = 0.89.

To multiply fractions, you simply multiply the numerators and then multiply the denominators. Follow these steps to find the product of -2/9 and 1/7:

Step 1: Multiply the numerators: -2 x 1 = -2
Step 2: Multiply the denominators: 9 x 7 = 63

Therefore, the product of -2/9 and 1/7 is -2/63.
