Answer:
In their House of Sound, Fran Scott and Greg Foot investigate how drums work.
Drums have been around for thousands of years and throughout history have often been involved in warfare -something they are reminded of as they play along to Mars from Holst’s The Planets suite.
Using confetti placed on a drum they use a slow motion camera to reveal how the confetti behaves like air molecules when the drum is struck.
The skin of the drum vibrates and makes the confetti dance.
As the air molecules vibrate against each other, sound waves are formed and the sound of the drums can be heard.
Fran explains that the pitch of a drum depends on how tight its skin is. If the skin is tight the drum makes a high note, if it is slack it makes a low note.
Greg points out the amount of air inside a drum also influences its pitch. The more air in a drum, the lower the note. The less air in a drum, the higher the note.
Volume depends on the size of the vibrations that are made.
Hit a drum hard and this makes big vibrations and a loud sound.
Hit a drum softly and the vibrations are smaller and the sound not as loud.
Together they make a drum kit out of things that can be found around the house, and Fran shows us how to make fun drums out of a plastic bowl and half a balloon.

Since you already changed the fractions into decimals, it will be easier to change it into fraction with the denominator of 100 or 1000.
All you have to do is move the decimals to the right in order to find the denominator.
14a) 50/100 OR 51/100 the bigger number would be 51/100 or 0.51
14b) 80/100 or 85/100 the bigger is 85/100 or 0.85
14c) 750/1000 or 734/1000 the bigger number is 750/1000 or 3/4.
Hope this helps.
