Answers
Answer:
5/8 + 2/8
= 2/12
= 1/6
Hence, Victor finished coloring in 1/6 hour more time than Jack.
3. Sarah purchased 3¹/₂kg apples and 4³/₄ kg oranges. What is the total weight of fruits purchased by her?
Solution:
Total weight of the fruits purchased by Sarah is 3¹/₂ + 4³/₄ kg.
Now, 3¹/₂ + 4³/₄
= 7/2 + 19/4
= (7 × 2)/(2 × 2) + (19 × 1)/(4 × 1)
= 14/4 + 19/4
= (14 + 19)/4
= 33/4
= 8¹/₄
Hence, total weight is 8 1/4 kg.
4. Rachel ate 3/5 part of an apple and the remaining apple was eaten by her brother Shyla. How much part of the apple did Shyla eat? Who had the larger share? By how much?
Solution:
We have, Part of an apple eaten by Rachel = 3/5
Therefore, part of an apple eaten by Shyla = 1 - 3/5
= 5/5 – 3/5
= (5 - 3)/5
= 2/5
Clearly, 3/5 > 2/5
So, Rachel had the larger share.
Now,
3/5 – 2/5
= (3 - 2)/5
= 1/5
Therefore, Rachel had 1/5 part more than Shyla.
5. Sam wants to put a picture in a frame. The picture is 7³/₅ cm wide. To fit in the frame the picture cannot be more than 7³/₁₀ cm wide. How much the picture should be trimmed?
Solution:
Actual width of the picture = 7³/₅ cm = 38/5cm
Required width of the picture = 7³/₁₀ cm = 73/10 cm
Therefore, extra width = (38/5 – 73/10) cm
= (38 × 2)/(5 × 2) – (73 × 1)/( 10 × 1) cm
= 76/10 – 73/10 cm
= (76 – 73)/10 cm
= 3/10 cm
