"Word problems"
| |
Help me do these word problems.
1.For every 150 seed you sow,97 germinate. At this rate, how many seeds will germinate if you sow 2550 seeds? n over 2550 times 97 over 150? or
2550 divided by 150 times 97 ?
====================================================
2. Spaghetti costs 79 cents for an 8 ounce box. Find the cost per ounce. Round to the nearest tenth of a cent. divide 8 into 79? = 9.875 or 10 cents per ounce
is there a formular that I should use to find the cost per ounce?
thanks |

You may be curious to have a look at the old CTK Exchange archive.
Please do not post there.
