1) At a concert, there are 3 times as many women as men. 3/5 of the men and 1/3 of the women wear glasses. There are 120 more women wearing glasses than men wearing glasses. How many people are at the concert.
2) The area of a rectangular invitation card is 3/10 square foot. Given that the length of the card is 4/5 foot, find its perimeter.
3/5m+120=1/3w 1/3w=m 3/5m+120=m subtract 3/5m frm both sides 120=2/5m multiply both sides by 5/2 to clear fraction 600/2=10/10m m=300 3m=w 3(300)=w w=900 900+300=1200 there were 1200 people at concert
2. so area =legnth times width 3/10=4/5 times x multiply both sides by 5/4 to clear fraction 15/40=x 3/8=width perimiter=2width+2legnth perimiter=2(3/8)+2(4/10) p=6/8+8/10 find lest commo multiply 8=2*2*2 10=2*5 LCM=2*2*2*5=40 6/8=30/40 8/10=32/40 p=30/40+32/40 p=62/40 perimiter=1 and 22/40 or 1 and 11/20 feet
