1. Answer :
Total number of days in an ordinary year = 365.
The zoo was open every day except three holidays.
So, total number of days that zoo opened = 362.
Total number of visitors in the year = 98646.
Therefore, number of visitors visited the zoo each day is nothing but the quotient when we divide 98464 by 362.
Let us use long division to estimate the quotient when we divide 98464 by 362.
Step 1 :
362 is greater than 9 and 98, so divide 984 by 362. Place the first digit in the quotient in the hundreds place. Multiply 2 by 362 and place the product under 984. Subtract.
Step 2 :
Bring down the tens digit. Divide 2,606 by 362. Multiply 7 by 362 and place the product under 2,606. Subtract.
Step 3 :
Bring down the ones digit. Divide the ones.
When we divide 98464 by 362, we get the quotient 272.
Hence, the average number of visitors per day last year was 272.
2. Answer :
Cost of each tube is nothing but the quotient when we divide 39 by 8.
Let us use long division to estimate the quotient when we divide 39 by 8.
Since 39 is not evenly divisible by 8, place a decimal point in the quotient. Add zeros to the right of the decimal point as needed.
Round to the nearest hundredth to find the dollar amount.
Therefore, the cost of each tube is about $4.88.
3. Answer :
The width of each lane is nothing but the quotient when we divide 9.76 by 8.
Let us use long division to estimate the quotient when we divide 9.76 by 8.
When we use the digit which comes after the decimal point, place a decimal point in the quotient directly above the decimal point in the dividend.
Therefore, each lane is 1.22 meters wide.
4. Answer :
The fee for one session is nothing but the quotient when we divide 153.86 by 14.
Let us use long division to estimate the quotient when we divide 153.86 by 14.
When we use the digit which comes after the decimal point, place a decimal point in the quotient directly above the decimal point in the dividend.
Therefore, the fee for one aerobics class is $10.99.
5. Answer :
To find the number of boxed that she needs to pack all of the books, we have to divide 1850 by 12.
So, let us divide 1850 by 12 using long division.
Quotient = 154
Remainder = 2
Callie can pack the books in 154 boxes perfectly and with 2 books left. So, she needs 155 boxes to pack all the books.
6. Answer :
Number of sheets of paper = 500
Number of classes to be divided = 3
500 = 166 x 3 + 2
Each class will get 166 papers and 2 papers will be left over.
7. Answer :
Number of biscuts i have = 40
Number of biscuts my younger brother have = 8
Number of times of biscuts i have = 40/8
= 5
8. Answer :
Number of pencils i have = 72
Number of pencils i have = 6(number of pencils my brother has)
Number of pencils my brother has = 72/6
= 12
9. Answer :
Length of ribbon i cut = 35 cm
Original length of ribbon = 8 x length of ribbon i have
= 8 (35)
= 280 cm
So, the original length of the ribbon is 280 cm.
10. Answer :
Weigth of my younger brother = 15 kg
Weight of my oldeer brother
= 3 x weight of my younger brother
= 3 x 15
= 45 kg
