First, start off by listing a few of the numbers that follow the first three clues to see if you can narrow it down. 7,111,111 7,333,333 7,555,555 etc. Then, start adding up digits to see if you're getting close. 7+1+1+1+1+1+1 = 13 7+3+3+3+3+3+3 = 25 7+5+5+5+5+5+5 = 37 Since 7,555,555 is too high, we step it down to 7,555,333 7+5+5+5+3+3+3 = 31 7,555,333 will work as an answer, as well as 7,333,555, since it's the same amount when the digits are added together.
So if you have 9 cats and they each have 9 kittens, then a reasonaable estimate is 10 times 9 since 10 is close to 9 so that is 90 and the answer is 81 you would knwo if you got 988387479 kittens if you got a problem because that is nowhere close to 90
If the scale is 32 to 1, that means it is 32 times bigger than the actual thing. So if the model is 196 inches long, then the actual heart is 196/32 inches long. This equals 6.125.
Answer, rounded to the nearest whole number: 6 inches.
