Marian wants to enlarge a picture she took that is 4 inches by 7.5 inches. she wants it to fit perfectly into a frame that is 400% of the original size.

what will be the dimensions of the new enlarged photo?

400% means the picture will be 4 times the original size.

Multiply each dimension by 4:

4 x 4 = 16

4 x 7.5 = 30

The new dimension will be 16 inches by 30 inches.

step-by-step explanation:

1gm = 1000mg so 0.1gm = 1000mg

first, convert the weight to kg

160lb * 1kg/2.2lb = 72.7kg

next, the dose

72.7kg * 100mg/kg = 7270mg
