Answer:
when adding you just line the decimals up like this, let's say you had to add 1 to 2.58.
2.58
+ <u> 1 .00</u>
3.58
when multiplying you might have to move it, say you had to multiply 1.5 by 2.2. (you don't have to line up the decimals like with addition)
1 .5
<u> </u><u>×</u><u> 2.2</u>
30
<u> </u><u>+</u><u> 300</u>
3.30
1.5 has one decimal place and 2.2 also has one decimal place so you put those 2 decimal places in your answer.
sorry if this is a bit confusing lol
Answer:
5 cakes
hope it helps
Step-by-step explanation:
if one cake feed 14 people and you are tying to fine out how many cakes you need to feed 60 people you would have to divide 60 by 14
1 cake = 14 people
? cakes = 60 people
60 ÷ 14 = 4.28
so in order to have enough for 60 people you need to round so you would need 5 cakes
to check you answer you can multiply 5 by 14 and you answer should be the amount of people
5 x 14 = 70
why cant it be 4? well because if you buy 4 cakes there wont be enough for 60 people and to make sure it wont be enough you can multiply 4 x 14
4 x 14 = 56
so 4 cakes only feeds 56 people so that is why your answer is 5 cakes are needed
