592 ÷ 30 = 592 × _______
To solve for the blank, we need to think about the relationship between division and multiplication. When we divide a number by another number, it is the same as multiplying by the reciprocal of that other number.
In this case, we are dividing 592 by 30, so we can find the missing number by writing 30 as a fraction with a numerator of 1:
30 = 1/30
So, 592 ÷ 30 is the same as 592 multiplied by 1/30:
592 ÷ 30 = 592 × 1/30
Simplifying 1/30 to its lowest terms by dividing both the numerator and denominator by their greatest common factor of 1, we have:
1/30 = 1 ÷ 30 = 0.0333333...
Rounding to the nearest hundredth, we have:
1/30 ≈ 0.03
So, the missing number is approximately 0.03:
592 ÷ 30 = 592 × 0.03
Mindi ran 4,506 meters on Monday and 2,549 meters on Tuesday. How many more meters did she run on Monday than on Tuesday?
To find out how many more meters Mindi ran on Monday than on Tuesday, we need to subtract the number of meters she ran on Tuesday from the number of meters she ran on Monday:
4,506 meters - 2,549 meters = 1,957 meters
Therefore, Mindi ran 1,957 more meters on Monday than on Tuesday.
