Answer:
1.28
Step-by-step explanation:
4/10 + 88/100
so this is unlike denominators so
4 times 10 and 10 times 10 equal to 40/100
so 40/100 + 88/100 equal to 128/100 so we simplify 128÷2 and 100÷2 equal to 64/50 and 64÷2 and 50÷2 equals 32/25 we do long division then it is equal to 1.28
If you divide 4.16 by 5.20 you get .8 which would be .80 cents a pound
Percentage error = 245-230/245 * 100 = 15/245 * 100 = 6.12%
After rounding off, it would be 6%
Answer: 0
35X +14=3X +14
35X = 3X
35X-3X=0
32X = 0 divide both sides by 32
x=0
