How many times greater is 70 million than 7 million

Mathematics
1 answer:
Dahasolnce [82]3 years ago
6 0

For this case we have the following expressions:

70,000,000

7,000,000

If we divide the first expression by the second we have:

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

Thus, we have that the first expression is 10 times greater than the second expression.

Answer:

70,000,000 is 10 times greater than 7,000,000

To help answer this question, Deigo wrote the division equation 3/4 divided by 2/5. Explain why this equation does not represent
Mars2501 [29]

Answer:

The fraction of the rain filled in the gauge will be =  \frac{8}{15}

Diego wrote the division equation incorrectly.

It must be given as \frac{2}{5} divided by \frac{3}{4} .

Step-by-step explanation:

Given:

After \frac{3}{4} of an hour of rain the rain gauge is \frac{2}{5} filed.

To find the fraction of the rain that will be filled in the gauge if it continues to rain at the same rate for 15 more minutes.

Solution:

15 minutes in hours will be = 15\ min \times \frac{1\ hour}{60\ min} = \frac{1}{4} of an hour.

Given that it has rained for \frac{3}{4} of an hour, and it continues to rain for  \frac{1}{4} of an hour more.

Thus, total time of rain will be = \frac{3}{4}+\frac{1}{4}=\frac{4}{4}=1\ hour

Using unitary method to find the fraction of rain filled in the gauge after 1 hour of rain.

If in  \frac{3}{4} of an hour of rain the rain gauge is \frac{2}{5} filed.

Thus, in 1 hour of rain the gauge will be filled by = \frac{2}{5}\div \frac{3}{4}

To divide fractions, we take reciprocal of the divisor and replace division by multiplication.

⇒ \frac{2}{5}\times\frac{4}{3}

⇒ \frac{8}{15}

Thus, the fraction of the rain filled in the gauge will be =  \frac{8}{15}

Diego wrote the division equation incorrectly.

It must be given as \frac{2}{5} divided by \frac{3}{4} .

What is the value of x in the equation? 7 1 2 x + 3 2 3 = −13 A) −1 5 6 B) −2 1 6 C) −2 2 9 D) −2 5 9
prohojiy [21]

Answer:

C - 2 2/9

Step-by-step explanation:

7 1 /2 x + 3 2/ 3 = −13

Subtract 3 2/3 from each side

7 1 /2 x + 3 2/ 3 - 3 2/3 = −13 - 3 2/3

7 1/2x = -16 2/3

Change each mixed number to an improper fraction

7 1/2 = (2*7 +1)/2 = 15/2

16 2/3 = (3*16+2)/3 = 50/3

15/2 x = -50/3

Multiply each side by 2/15 to isolate x

2/15 * 15/2 x = -50/3 * 2/15

x = -100/45

Simplify

x = -20/9

Change back to a mixed number

9 goes into 20 2 times with 2 left over

x = -2 2/9

Solve the inequality. 4a < 52
jeka57 [31]

4a<52

All you have to do is divide 4 from a and 52.

4a<52

/4   /4

a<13

a<208 √

a<56 √

a<48 √

a<13 X

So the odd one out is a<13
