Answer:

7, 49

Step-by-step explanation:

7 is double 3 1/2, so if one number is doubled, the other must be halved for the equation to work. 3.5 x 14 is 49, and 7 x 7 is 49

Please help :) (Filler text incoming) <br><br> aaaaaaaaaaaaaaaaaaaaaaaa
jekas [21]
Hello!

First you divide 1/3 and 6/7

1/3 / 6/7 = 7/18

Now you make the two fractions have the same denominator

5/6 = 15/18

Now add

7/18 + 15/18 = 22/18

Simplify

11 / 9

The answer is 11 / 9

Hope this helps!

Ann's penny bank is 1/2 full. After she adds 120 pennies, it is 2/3 full. How many pennies can Ann's bank hold?
joja [24]

Her bank can hold 360 pennies.

Explanation:

Her bank was half full. Then, when she adds 120. It is 2/3. This would mean the 120 is 2/6 the amount the bank can hold. You would multiply that by 3 to get the total amount. That amount being 360.

Do you have any questions? Did I calculate something wrong?

Please tell me! I am happy to help people!

scale drawing: Steve drew a scale drawing of the town library. The parking lot, which is 45 meters wide in real life, is 126 cen
Veseljchak [2.6K]

Answer:

1.05 cm = 75 cm

Step-by-step explanation:

First, convert 45 meters into centimeters. You will get 4500 centimeters. Then, convert the numbers into a fraction form (126/4500). Divide the numerator and denominator by 15 to get 4.2/300. If you then divide them both by 4 you will get 1.05/75. This means that every 1.05 cm on the paper represents 75 cm of the real life lot.
