Tom had 7/12 of a pizza. His little sister came along and took 2/5 of his pizza away. How much pizza does Tom have left?

Answers

Answer 1

Answer: To find the answer,we can first calculate how much her sister took away by multiplying the original amount he has to the amount her sister took.

Her sister has:
7/12×2/5
=7/30

We can then find the amount of pizza left by deducting the pizza he has to the answer we found above:

7/12-7/30
=35/60- 14/60
=21/60
=7/20

Therefore he has 7/20 of a pizza left.

An alternative way to find the answer:
7/12×(1-2/5)
=7/12×3/5
=7/20

Hope it helps!

36,204+40,918 estimate then find the sum

Answers

Estimated guess 77,000 actual sum 36,204 + 40,918 = 77,112

First you need to round the numbers:

36,204 = 36,000
40,918 = 41,000

Now that the numbers are rounded it is easy to add them:

36,000 + 41,000 = 77,000

What is the solution to 1/3x-5+171=x

Answers

(1/3)x-5+171=x
I move the x on the right to the left so
(1/3)x-x-5+171=0
I then simplify so
(-2/3)x+166=0
I subtract 166 from both sides so
(-2/3)x = -166
Then I divide (-2/3) from both sides so
x = -166/(-2/3)
x = 249
and that's the answer
hope this helps

x in (-oo:+oo)

(1/3)*x-5+171 = x // - x

(1/3)*x-x-5+171 = 0

166-2/3*x = 0 // - 166

-2/3*x = -166 // : -2/3

x = -166/(-2/3)

x = 249

x = 249
