Answer:
5
Step-by-step explanation:
do reverse calculations
we know that we ended with 6
since 2 jumped out we add them back in
6+2 = 8
we remove the toads that jumped in because they are not part of the original group
8-3 = 5
there were 5 toads in the beginning
D should be the correct answer
Answer:
28
Step-by-step explanation:
the highest is 30 subtract that by 2 because it is 2 spaces below and then your answer should be 28
Answer:
Total paint left over = ![\frac{13}{12}L](https://tex.z-dn.net/?f=%5Cfrac%7B13%7D%7B12%7DL)
Step-by-step explanation:
Given - To paint a house, 5/4 L of white paint and 1/2 L of blue paint
were mixed. In the end only 2/3 L of the mixture were used.
To find - How many liters of paint were left over ?
Proof -
Given that,
5/4 L of white paint and 1/2 L of blue paint were mixed.
So, total mixture =
= ![\frac{5 + 2}{4}L](https://tex.z-dn.net/?f=%5Cfrac%7B5%20%2B%202%7D%7B4%7DL)
= ![\frac{7}{4}L](https://tex.z-dn.net/?f=%5Cfrac%7B7%7D%7B4%7DL)
⇒Total mixture = ![\frac{7}{4}L](https://tex.z-dn.net/?f=%5Cfrac%7B7%7D%7B4%7DL)
Now,
Given that ,
In the end only 2/3 L of the mixture were used.
So, total mixture left = ![(\frac{7}{4} - \frac{2}{3})L](https://tex.z-dn.net/?f=%28%5Cfrac%7B7%7D%7B4%7D%20-%20%5Cfrac%7B2%7D%7B3%7D%29L)
= ![\frac{21 - 8}{12}L](https://tex.z-dn.net/?f=%5Cfrac%7B21%20-%208%7D%7B12%7DL)
= ![\frac{13}{12}L](https://tex.z-dn.net/?f=%5Cfrac%7B13%7D%7B12%7DL)
∴ we get
Total paint left over = ![\frac{13}{12}L](https://tex.z-dn.net/?f=%5Cfrac%7B13%7D%7B12%7DL)
