Newtons recipes for 32 biscuits calls for 2 and 1/4 of flour. How much flour will Newton need to make 224 biscuits?
F. 15 cups
G. 15 and 1/2 cups
H. 15 and 3/4 cups
J. 18 and 1/2 cups

Answer 1

convert 2 1/4 into proper function =9/4
32 biscuits require 2 and 1/4
then 224=32*x=>(9/4)*x
here u have to find x and substitute in (9/4)*x
u will get answer

Answer 2

I don't get you o.o

Answer 3

i mean 2 1/4 should be (2*4+1)/4, u get 9/4
u know that 224=32*8
if 32 biscuits take 9/4 flour,
then 32*7 takes= 9/4*7=63/4 flour
convert it back to improper function

Answer 4

or u can directly multiply, 2 and 1/4 with 7, u get
14 and 7/4, and 7/4 can be written as 1 and 3/4
so 15 3/4 should be ans
