✏️. Answer

= 0.26

0.22+0.04= [ 0.26 ].

OTHERS EXAMPLE:

Fraction: 2/10 × 4/10= 8/100

Decimal: 0.2 × 0.4= 0.08

If we multiply the tenth by four tenths, we get a product of eight hundred.

• In the problem above the product 0.08 is smaller than each individual factor. this is because you are finding apart of apart: 2.0 of 4.0 is 0.08. Thus, when you multiply two decimal factors, where each is less than one, the product will be less than each individual factor.

Another example:

Estimate the product:

Round both factors down.

44.8 ➡️ 40 × 10=100

× 15.4 ➡️➡️➡️➡️⬆️

Round both factors up.

44.8 ➡️ 50 × 20=1,000

× 15.4 ➡️➡️➡️⬆️

the product of 44.8 and 15.4 ranges from 400 to 1,000.

Multiply to find the product:

multiply these decimals as if they were whole numbers. ignore the decimal point.

44.8

× 15.4

= 17 92

224 00

= 689 92

Compensate by placing the decimal point in the product:

44.8 ⬅️ 1 decimal digit

×15.4 ⬅️ 1 decimal digit

= 17 92

224 00

= 689 92 ⬅️ 2 decimal digit

Comapare your estimate with your product to verify that your answer makes sense:

Our answer of 682.92 makes sense since the product of 44.8 and 15.4 ranges from 400 to 1,000.
