Answer:

The answer is 39.2

Step-by-step explanation:

The first thing you want to do is multiply both numbers by them selves like this: 9x8 and 4x8. Then after you do that, add the sum of those equations and you have your answer. Think about it like this, for 8x4, all it is is just 8+8+8+8. If solving it that way is easier for you, go for it! Hope I could help!

John wrote the numbers 678,901 and 67,890. How many times greater is the value of 7 in 678,901?

worty [1.4K]

Answer:

The value of 7 in 678,901 is 10 times greater than the value of 7 in 67,890

Step-by-step explanation:

step 1

we have

678,901

Write in expanded form

678,901=600,000+70,000+8,000+900+1

The value of 7 is 70,000

step 2

we have

67,890

Write in expanded form

67,890=60,000+7,000+800+90

The value of 7 is 7,000

step 3

Divide 70,000 by 7,000

$\frac{70,000}{7,000}=10$

therefore

The value of 7 in 678,901 is 10 times greater than the value of 7 in 67,890
