What number is 7 times as much as 9
The Correct Answer and Explanation is:
To find a number that is 7 times as much as 9, you simply multiply 9 by 7.
Calculation:
[
9 \times 7 = 63
]
So, the number that is 7 times as much as 9 is 63.
Explanation:
When we are asked to find “7 times as much as” a number, we are essentially being asked to multiply that number by 7. This operation is based on the mathematical principle of multiplication, which is repeated addition. In this case, multiplying 9 by 7 means adding 9 a total of 7 times. Let’s break it down:
[
9 + 9 + 9 + 9 + 9 + 9 + 9 = 63
]
Thus, by adding 9 seven times, we arrive at the same result, 63. Multiplication is a quicker way to express this repeated addition.
Real-World Application:
Multiplication is used extensively in daily life. For example, if you have 9 apples and someone gives you 7 times as many apples, you would receive 7 sets of 9 apples. This means you would have 63 apples in total. Another example could be when you’re calculating the total cost of an item. If each item costs 9 dollars and you want to buy 7 items, multiplying 9 by 7 will give you the total cost.
Why Multiplication Works:
Multiplication is essentially a shortcut for repeated addition. It allows us to scale numbers quickly, making it easier to handle larger numbers or solve more complex problems. The operation ( 9 \times 7 = 63 ) is much quicker than adding 9 repeatedly. This is the basic principle behind multiplication, whether it’s in simple arithmetic or more advanced mathematics.
