Answer:
4613203
Step-by-step explanation:
To round as a whole number, take the decimals and see what the first number of the decimal is. if the number is 5 or more, its 1 more number. if its lower than 5, its not a whole number.
3/4 - per skirt >> 0.75
5 5/14 - unused >> 5.36 (approximately)
5.36/0.75= 7.14666...
Regina can make 7 skirts
13=3+10
so it is now
3+10-7
we know that 10-7=3 so we now have
3+3=6
tada
