A)
\n" ); document.write( "to write these numbers as millions or billions, we put the whole millions/billions in front of the decimal point and write the other non-zero digits after the decimal point.
\n" ); document.write( "this number, in words, is 44 million, 500 thousand. so we have 44 whole millions.
\n" ); document.write( "i.e. 44.5 million
\n" ); document.write( "B)
\n" ); document.write( "This number in words is 7 billion, 220 million. so we do the same again
\n" ); document.write( "put the 7 in front of the decimal point and the other non zero digits after it, so we get
\n" ); document.write( "7.22 billions, this needs to be rounded to 1 decimal place which means we have
\n" ); document.write( "7.2 billion
\n" ); document.write( "C)
\n" ); document.write( "This number in words is 3 million, 110 thousand. Doing the same again gives
\n" ); document.write( "3.11 million, rounded to
\n" ); document.write( "3.1 million
\n" ); document.write( "D) here we have 8 million, so that's it!
\n" ); document.write( "8 million
\n" ); document.write( "E)
\n" ); document.write( "2 billion, 550 million so we have
\n" ); document.write( "2.55 billion which needs rounding (careful with the rounding on this one!) giving
\n" ); document.write( "2.6 billion
\n" ); document.write( "F)
\n" ); document.write( "this number is 425 million, we can write this in two ways either as millions or billions!
\n" ); document.write( "writing as millions we have
\n" ); document.write( "425 million
\n" ); document.write( "thinking of this as billions we get
\n" ); document.write( "0.425 billion, which we can round to
\n" ); document.write( "0.4 billion! This is quite inaccurate though so i would probably stick with writing this as millions.
\n" ); document.write( "
\n" ); document.write( "
\n" );
