Answer: 40</h3>
Explanation
We can only keep one of the digits: either the tens digit or the units digit. If we kept only the units digit, then we go from 39 to 9 which is a very steep drop. If we kept the tens digit then we go from 39 to 30
The 0 in the "30" is not significant. It's just a placeholder to help us tell 30 apart from simply 3. The drop from 39 to 30 is much smaller (compared to from 39 to 9). But you can probably see that it's even better to bump up to 40 instead, due to the smaller change.
In short, 39 rounds up to 40 when rounding to one significant digit.
Answer:
44
Step-by-step explanation:
Given that Krutika gets 33 sweets which is 3 parts of the ratio.
Divide this amount by 3 to find the value of one part of the ratio
33 ÷ 3 = 11 ← 1 part of the ratio, thus
David gets 1 × 11 = 11 sweets and
Mark gets 5 × 11 = 55 sweets, thus
55 - 11 = 44 ← number of sweets Mark gets over David
if p-q is a true statement and p is true ,then q is true
