How could the partial strategy be applied to 2 digit by 2 digit multiplication problem?

1 answer:

4 0

The partial product method involves multiplying each digit of one number in turn with each digit of another where each digit keeps its place. (So the 2 in 23 would actually be 20.) For example, 23 x 42 would become (20 x 40) + (20 x 2) + (3 x 40) + (3 x 2).

What number goes on top and how do you solve it.

So basically, each number is equal to the two numbers below it added together.

See, 7 = 3+4, 8 = 5 +3, etc.

So, the top would be 16 + 17.

16 + 17 = 33

So 33 goes on top.

<u>Find fraction of snappers and catfish:</u>

1/3 + 2/9 = 3/9 + 2/9 = 5/9

<u>Find fraction of goldfish:</u>

1 - 5/9 = 4/9

4/9 = 40 goldfish

1/9 = 40 ÷ 4 = 10

9/9 = 10 x 9 = 90

if you multiply the number by 2 and add 4, then result you get will be the same as three times the number decreased by 7.
