`\bold{\huge{\green{\underline{Solution }}}}`

`\bold{\underline{ Given :-}}`

• We have given that , The cooking time for a leg of lamb is 2/5 hours for each pound

`\bold{\underline{ To \: Find :-}}`

• We have to find , how long should we cook a leg of lamb that weighs 12 3/4 pounds .
• How many hours before we have to cook the food so that it will be ready on time for dinner ?

`\bold{\underline{ Let's \: Begin :-}}`

Answer (a) :-

According to the question,

`\sf{( 2)/(5)}{\sf{ \:hours = 1 \:pound }}`

Therefore,

`\sf{ For \: 12}{\sf{( 3)/(4)}}{\sf{\: hours}}`

`\sf{ = }{\sf{( 51)/(4)}}{\sf{ × }}{\sf{(2)/(5)}}`

`\sf{ = }{\sf{( 102)/(20)}}`

`\sf{ = 5.1 \: hours }`

`\sf{\red{ = 5\: hours\: 6\: minute }}`

Hence, To cook a leg of lamb weighs 51/4 pounds requires 5 hours 6 minutes

Answer ( b) :-

We have to start cooking before atleast 5.2 hours so that food is ready on the Time for dinner.

• 5.2 hours because serving and dressing of food also take some time.
