Problem |
Mother purchased 9 kg 357 mg of sweets and snacks for the occasion. Out of which 6 kg 458 mg were consumed. What quantity of sweets and snacks were left? |
|
2 |
Step |
Initial quantity is |
9 kg 357 mg |
3 |
Step |
Consumed quantity is |
6 kg 458 mg |
4 |
Formula: |
To find the quantity left, you need to subtract the consumed quantity from the initial quantity: |
\$"Initial quantity" − "Quantity consumed" = "Quantity left"\$ |
5 |
Step |
First, ensure that the units are consistent. If you convert everything to grams for accuracy |
|
6 |
Step |
\$"Initial quantity" = 9 "kg" 357 "mg"\$ ⇒ \$9"kg" times (1000"grams")/"kg" + 57"mg" times (0.001"grams")/"mg"\$(1 kg = 1000 grams, 1 mg = 0.001 grams) ⇒ \$9000"grams" + 0.357"grams"\$ ⇒ \$9000.357"grams"\$ |
|
7 |
Step |
\$"Quantity" "consumed" = 6 "kg" 458 "mg"\$ ⇒ \$6"kg" times (1000"grams")/"kg" + 458"mg" times (0.001"grams")/"mg"\$ ⇒ \$6000"grams" + 0.458"grams"\$ ⇒ \$6000.458"grams"\$ |
|
8 |
Formula: |
Formula Now, subtract the quantity consumed from the initial quantity: |
\$"Quantity left" = "Initial quantity" − "Quantity consumed"\$ |
9 |
Step |
Values substituted in the formula |
\$9000.357"grams" − 6000.458"grams"\$ |
10 |
Step |
After simplification, we get |
\$2999.899 "grams"\$ |
11 |
Step |
Therefore, after 6 kg 458 mg of sweets and snacks were consumed from the initial 9 kg 357 mg, 2,999.899 grams of sweets and snacks were left. |
