Answer:
25 pounds.
Step-by-step explanation:
1 kg = 2.2 pounds
11.5 kg = x pounds Cross Multiply
1 * x = 11.5 * 2.2
Since you are estimating the question, you don't use a calculator. So 11.5 * 2
23 pounds. 11.5 * 0.2 = 2.3 pounds
Total = 23 + 2.3 = 25.3
So the total is more than 25 but way less than 30
You can make the question a bit more formal by noticing what I did was related to the distributive property.
11.5 ( 2 + 0.2) Remove the brackets.
11.5 * 2 + 0.2*11.5 Which gives you exactly the same thing as above.
To solve do the base (2.2) multiply by the height (3.8) and then divide the answer I get from that by 2
