Question

what is the meaning of this question please tell me​

Answer 1

Answer:

at first 12 is split up into 10+2

then both 10 and 2 are multiplied by 5 as both are in bracket

then the value of 5*10 and 5*2 are written

then at last the answer are added and the required number are got

Answer 2

See dear!!

5×12=60 we know that..

They have asked to expand and write. So,

5×12 = 5×(10+2) } here we have to multiple 5 to both the number. Since it is the factors of 12.

Next step:

(5×10) + (5×2)

You may have a question that Why we did not add 10+2 in the above step. This is because of Bodmas. According to this we have to multiple first. So we multiplied it first. Okay!!

Next Step:

50 + 10 } After multiplying the above step we get this answer.

So the last answer is 60.

If we do the direct method also we get the same answer dear!!

Hope it helps(•ө•)♡
