Maria bought a bag of flour so that she can make muffins it has a mass of 2.26 kg Shanice 450 g of flour to make one batch of mu
xenn [34]

Answer:

10 grams or 0.010kg

Step-by-step explanation:

The mass of the bag used to make flour is 2.26 kg = 2260 grams

Now, in order to find out how many badges she made, we would need to divide the weight of the bag by the amount needed to make a badge.

Therefore: \frac{2260}{450}  = 5.02

We know now that the bag will make 5 batches and will have some left over. In order to find how much we used, we can multiply 5 * 450 = 2250.

Therefore, in order to make 5 batches, Maria used exactly 2250 grams of flour which in result left us with 10 grams of the bag.

Note: 2260 -2250 = 10 grams.

Subtract, in order to find how many you have left.

Hope this helps.
