Estimating Products
Example 1: 78.
Example 2: 437.
Example 1: 80 x 30.
Example 2: 40 x 700.
Step 1: Round 2 and 3 digit numbers to the nearest ten or hundred. Do not round one-digit numbers.
Step 2: Multiply the non-zero digits.
Step 3: Write the number of zeroes in the rounded numbers on the end of the answer.
Answer:
60m tall
Step-by-step explanation:
Since this is a ratio problem and we are given 3 values and 1 unknown then we can use the Rule of Three to calculate the height of the tower which we will refer to as x. The Rule of Three simply multiplies the diagonal values and divides by the third value in order to get the missing unknown like so...
12m height <======> 8m shadow
x height <======> 40m shadow
(40m * 12m) / 8m = 60m height
Finally, we can see that the height of the tower is 60m tall.
