10. Simplify: (2mks)
253/2 x 9 ½ x 22
52 x 3
The simplified expression is:
253/2 x 9 ½ x 22
To simplify, we can first convert the mixed number 9 ½ into an improper fraction:
9 ½ = 19/2
Now we can multiply the fractions:
(253/2) x (19/2) x 22 = 253 x 19 x 22 / (2 x 2)
= 114514 / 4
= 28629
So, the simplified expression is 28629.
To simplify the expression (2mks) 253/2 x 9 ½ x 22 x 52 x 3, follow these steps:
Step 1: Simplify the fraction 253/2 by dividing the numerator (253) by the denominator (2).
253 ÷ 2 = 126.5
Step 2: Multiply 126.5 by 9 ½. Convert the mixed number 9 ½ to an improper fraction:
9 ½ = 19/2
Multiply 126.5 by 19/2.
126.5 x 19/2 = 1203.25
Step 3: Multiply the result from Step 2 (1203.25) by 22.
1203.25 x 22 = 26471.5
Step 4: Multiply the result from Step 3 (26471.5) by 52.
26471.5 x 52 = 1375878
Step 5: Finally, multiply the result from Step 4 (1375878) by 3.
1375878 x 3 = 4127634
Therefore, the simplified expression for (2mks) 253/2 x 9 ½ x 22 x 52 x 3 is 4127634.
