Can someone solve and explain part a, b and c

Part A

Step-by-step explanation:

Part A is asking for the ratio. Ratio is the quantitative relation between two amounts showing the number of times one value contains or is contained within the other. You ave the make the denominators the same so 3/4 turns to 6/8 and 1/8 so it is a 6:1 ratio.

Then it is asking for how you can fit it he added 8/8 instead of 1/8  that is 8 times the amount it was asking for so now you add 8 times the amount of sugar so 6/8 * 8 = 48/8 which is also just 6 cups of sugar.

21/58.

hope to be marked brainliest

step-by-step explanation:

well if you round, things become much more simple. round 5.95 to 6, 4.25 to 4, and 1.05 to 1. now, add 6+4+1 and that would equal 11. so the items together would equal to about $11.
