Description:

Explanation	Answer
Problem	Thomas ran \$5/12\$ of a km yesterday and \$1/6\$ of a km today. How much more distance did he run yesterday than today?
Operator used	-
Step - 1	Number of km ran by Thomas yesterday = \$5/12\$
Step - 2	Number of km ran by Thomas yesterday = \$1/6\$ ⇒ \$1/6 \times 2/2 = 2/12\$ [∴ Here we multiply with 2/2 to get same denominator]
Step - 3	Much more distance that he run yesterday than today = \$5/12 - 2/12 = 3/12\$
Step - 4	Hence, \$3/12\$ km much more distance that he run yesterday than today.

Explanation

Answer

Problem

Thomas ran \$5/12\$ of a km yesterday and \$1/6\$ of a km today. How much more distance did he run yesterday than today?

Operator used

Step - 1

Number of km ran by Thomas yesterday = \$5/12\$

Step - 2

Number of km ran by Thomas yesterday = \$1/6\$
⇒ \$1/6 \times 2/2 = 2/12\$ [∴ Here we multiply with 2/2 to get same denominator]

Step - 3

Much more distance that he run yesterday than today = \$5/12 - 2/12 = 3/12\$

Step - 4

Hence, \$3/12\$ km much more distance that he run yesterday than today.
