Explain why you can use subtraction to solve a division problem.

Subtraction is finding the difference between two numbers whereas division is putting numbers into equal pairs or undoing multiplication ( if that helps ) So... If they say divide 6 by 2 they mean put six into equal pairs of 2 which would equal 3 E.g.:- ( there are 3 pairs of six cars in twos ) You can't use subtraction because that will just find the number difference of 6 and 2 which is 4 Hope that wasn't complicated

PLEASE HELP! I HAVE TWO QUESTIONS AND WILL GIVE 100PTS AND BRAINLIEST IF CORRECT!
Volgvan

Answer:

1) $283.50

2) 65.21 meters.

Step-by-step explanation:

Part 1)

We know that a spool of ribbon holds 6.75 meters.

A craft club buys 21 spools.

So, the total length of ribbon bought is:

T=21(6.75)=141.75\text{ meters}

Each meter costs $2. So, the total cost will be:

141.75(2)=\$ 283.50

Part 2)

A spool holds 6.75 meters.

We bought 21 of them, so that total length we have is 141.75 meters.

The club used 76.54 meters.

So, the amount of ribbon that is left is represented by:

141.75-76.54

Subtract:

=65.21\text{ meters}

So, 65.21 meters of ribbon will be left.
