Step-by-step explanation:
The given numbers are : 42, 60 and 78
On Prime Factorization of the given terms, we get:
42 = 2 x 3 x 7
60 = 2 x 2 x 3 x 5
78 = 2 x 3 x 13

Answer:
Step-by-step explanation:
When 448 is rounded to the nearest tens then the value is 450.
When rounding a number to the nearest tens, we consider the digit in the tens place.
In the case of 448, the digit in the tens place is 4.
To round to the nearest tens, we examine the digit in the ones place, which is 8. Since 8 is greater than or equal to 5, we round the tens place up by 1.
Therefore, the digit in the tens place becomes 5, and all the digits to the right of the tens place become zeros.
This gives us the rounded value of 450.
