Find the product or quotient for each. simple form<br> 5/9 divide 5/6
MakcuM [25]

Answer: 2/3

Step-by-step explanation:

5/9 and 5/6 doesn't have the same denominator. So 5/9 changes to 10/18, while 5/6 changes to 15/18.

10/18 divided by 15/18= 10/18 x 18/15 = 180/270

180/270= 2/3

Tom has a large photo he wants to shrink to wallet-sized. It's width is 20 centimeters and it's len is 30 centimeters. If he wan
dsp73
We can use ratios, in other words, if one part of the photo is changed x times, how many times does the other part change?

We can set up the proportion as :
width 1 : length 1 = width 2 : length 2

20 : 30 = 5 : x

We do inverse multiplication, or multiply the outer with outer and inner with inner (W1 * L2 and L1 * W2)

20*x = 30*5
20x = 150
Divide all by 10
2x = 15
Divide all by 2 to isolate x
x = 15/2
x = 7.5cm

What is the partial product for 1,262 x 3
puteri [66]

Step-by-step explanation:

what is THE partial product ? there is a mistake in your problem description.

it must read "what are valid partial products".

1262×3 has the following partial products :

1000×3 = 3000

200×3 = 600

60 × 3 = 180

2×3 = 6

-----------

3786

so, D seems to be the best answer, because both numbers are partial products here.

A, B and C have each only one correct.
