Mr. Snow bought 90 grams of Christmas candy for each of his 14 grandchildren. How many total kilograms of candy did he buy?

nignag [31]

Answer:

1.26 kg.

Step-by-step explanation:

We have been given that Mr. Snow bought 90 grams of Christmas candy for each of his 14 grandchildren. We are asked to find the amount of candy bought by Mr. Snow in kilograms.

First of all, we will find the amount of candy in grams by multiplying 90 grams by 14 as:

$\text{Amount of candy bought in grams}=14\times 90$

$\text{Amount of candy bought in grams}=1260$

We know that 1 kilogram is equal to 1000 grams. To convert 1260 grams into kg, we will divide 1260 by 1000 as:

$\text{Amount of candy bought in kilograms}=\frac{1260}{1000}$

$\text{Amount of candy bought in kilograms}=1.26$

Therefore, Mr. Snow bought 1.26 kilograms of candy.

Adrianne is planning to bake some chocolate, strawberry, and raisin muffins for a party. She was asked to bake half as many choc

Genrish500 [490]

Answer: She can bake 160 raisin muffins.

Step-by-step explanation:

Let the number of raisin muffins be 'x', then

The number of chocolate muffins = $\frac{1}{2}x$

The number of strawberry muffins= $3\times(\frac{x}{2})=\frac{3x}{2}$

Since, the total muffins she can bake 480.

Therefore,

$x+\frac{x}{2}+\frac{3x}{2}=480\\\Rightarrow\frac{2x+x+3x}{2}=480\\\Rightarrow\frac{6x}{2}=480\\\Rightarrow\ x=\frac{480\times2}{6}\\\Rightarrow\ x=160$

Hence, she can bake 160 raisin muffins.
