So, adding two rationals is the same as adding two such fractions, which will result in another fraction of this same form since integers are closed under addition and multiplication. Thus, adding two rational numbers produces another rational number.
a/b and c/d are rational numbers with a,b,c,d intergers
so with the same denominators ( equaling a+c over b) or different ones (equaling ab+cb over bd) they end up with the answers of
same denominator= b is not equal to 0
different denominators= d is not equal to 0
this may not make sense but i'm pretty sure i understood you right
Amount of liquid plant fertilizer in the container that the gardener has = 6 1/5 pounds
= 31/5 pounds
We already know that 1 pound = 16 ounce
Then
Amount of liquid plant fertilizer in the
container that the gardener has = (31/5) * 16 ounce
= 496/5 pounds
Amount of liquid plant fertilizer that the gardener uses on Sunday = 2 1/2 ounces
= 5/2 ounces
Then
The amount of liquid plant fertilizer that are left= (496/5) - (5/2) ounces
= (992 - 25)/10 ounces
= 967/10 ounces
= 96.7 ounces
So the total amount of liquid plant fertilizer left is 96.7 ounces.

Answer:
Green Material: <u>129.6</u> in³
Brown Material: <u>194.4</u> in³
Step-by-step explanation:
The volume of the bin is 4×18×9 in³ or 648 in³
20% of 648 is 129.6 in³ (brown material)
30% of 648 is 194.4 in³ (green material)
1) find how many rocks Nellie counted by subtracting 156 from 336
336 - 156 = 180 rocks <- Nellie
2) find how many rocks Pat counted by adding 418 to 336
336 + 418 = 754 rocks <- Pat
3) find how many rocks Nellie and Pat counted by adding 180 and 754 together
180 + 754 = 934 rocks <- Nellie and Pat
4) your answer is 934 rocks, which is B
Hope this helped!
