13. we can summarize as follows: sophia used 1/6 of the 4/8 yard of string, therefore sophia used

--> sophia used 1/12 of yard.

23. the conversion factor is 1 c = 8 fl oz, therefore we must multiply by 8:

4 1/8 c = 4 fl oz

24. we have 65 inches. the conversion factor between inches and feet is:  

1 ft = 12 in

therefore, we should divide 65 inches by this factor to obtain the measurement in feet:

25. mai-li has yd of material. the new skirt takes yd. so, the material left will be

yd

26. to find the difference 6/25 - 4/5, we should choose 25 as common denominator, since it can be divided by both 25 and 5. therefore we have:

27. total mulch: pounds

each bag can hold pound

a: number of full bags filled with mulch:   --> 17 full bags

b: total price: 17 * 2.25 $/bag=38.25 $

28. shayla needs:

29. the basic recipe serves 8 people. we need the amount of each ingredient to serve 32 people, so we must multiply the amount of each ingredient by 32/8=4:

dried split peas:

water cup:

chopped onion:

cup chopped celery:

ham shank: pounds

30. 1 pound = 16 ounces

therefore, we must divide 96 ounces by 16 in order to convert into pound:

96 ounces/16= 6 pounds
