How do i solve 500x3 please help

1500

Step-by-step explanation:

0ne way to think about multiplication that helps me sometimes is to think of it as repeated addition

so instead of it being 500*3 it says 500+500+500

500+500=1000

1000+500=1500

since 500 is 5 with 2 zeros you can take away them and make it 3x5=15

then add the two zeros back again and you get 1500 so 1500 is your answer

hope i helped

Step-by-step explanation:

d. bc = 12 and ef = 16

step-by-step explanation:

we are given that δabc : δdef such that .

also, it is given that

so, from the options, we need that .

a.

b.

c.  

d.

as, we can see that only option d gives the same ratio as i.e. .

hence, the possible lengths are bc = 12 and ef = 16.
