Answer:
At first it increases by 25%, then you have 1.25x the original temp. A drop of 40% gives you .6 x 1.25, or 75% of the original temperature
Step-by-step explanation:
found that on the web for yuh. I really hope it helped.
Answer:
need more detail to answer correctly
Step-by-step explanation:
40/100×120=4/1×12=48. 1/4×200=50. so 1/4 of 200 is greater than 40% of 120.
Answer:
a. (8 × 2) = (2 + 2 + 2 + 2 + 2 + 2 + 2 + 2) = 16
b. (8 × 2) = (2 × 8) = (8 + 8 ) = 16 {Using the commutative property}
c. It is easier to calculate (8 + 8 ) than (2 + 2 + 2 + 2 + 2 + 2 + 2 + 2).
Step-by-step explanation:
Multiplication operation is equivalent to the repeated addition operation.
For example (3 × 4) can be treated as 3 groups of 4 or 4 + 4 + 4 then use the addition facts to learn the multiplication facts.
a. Now, (8 × 2) can be treated as 8 groups of 2 or 2 + 2 + 2 + 2 + 2 + 2 + 2 + 2 then using the addition facts we get (8 × 2) = (2 + 2 + 2 + 2 + 2 + 2 + 2 + 2) = 16
b. If we apply the commutative property of multiplication then (8 × 2) = (2 × 8) and we can assume it as 2 groups of 8 or (8 + 8) i.e. 16 which makes it easier to get the multiplication process by addition operation.
c. It is clear that (8 + 8) is much more easier to calculate than (2 + 2 + 2 + 2 + 2 + 2 + 2 + 2) by addition operation. (Answer)
